系统信息

我使用的是相对较新的 Dell XPS，运行的是 Ubuntu 18.04。它有一个 Intel VGA 控制器和一个 Nvidia 3D 控制器。

几天前，笔记本电脑的分辨率卡在了 960x540，所以我通过NVIDIA-Linux-x86_64-390.116.run以下网址安装了 Nvidia 驱动程序 v390：https://www.nvidia.com/object/unix.html.（为安全 UEFI 启动而对内核模块进行签名是一次冒险）。

编辑2：我禁用了安全启动，删除了手动安装的nvidia-390，并使用

sudo add-apt-repository ppa:oibaf/graphics-drivers && sudo apt update

，然后改为sudo ubuntu-drivers-autoinstall。这不会带来任何变化，只是nvidia kernel module现在已加载gpu-manager.log（如下所述）。

我禁用了 Wayland 作为 XDG_SESSION_TYPE、将 nouveau 列入黑名单等等。

昨晚我的系统成功启动，并提供了各种分辨率选项。然而，今天启动笔记本电脑时，屏幕变黑（尽管它发出了登录屏幕通常会发出的恼人声音）。

我设法按 Ctrl-Alt-F4 进入终端并稍微弄了一下，但无济于事。最后，当我在以前的内核版本上以恢复模式启动时，我能够启动 X 服务器。

编辑：重新启动进入不良状态并获取所有实际信息，现已发布在下面。

以下是一些相关命令的输出。

问题

出现的情况是，nvidia 驱动程序成功加载，但由于某种原因，intel 驱动程序没有与 Intel VGA 设备关联，但我不知道原因。

我如何让 Ubuntu 再次将英特尔驱动程序绑定到我的 VGA 卡？正确方向的指针将会很有帮助。

答案1

啊哈，那是因为我排nomodeset在/etc/default/grub队伍里

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset i915.alpha_support=1"

并且 i915 驱动程序需要能够设置模式。感谢 archlinux wiki 指出这一点：https://wiki.archlinux.org/index.php/Intel_graphics#Loading

另一方面，我现在又回到了我的最大分辨率是 960x540 的问题，但那是另一回事......
